SPLE'EDI-REGULATINGJMECHANISM F63 GAS-ENGINES,

No. 824,105. a

Be it known that I, GEORGE H. ELLIS, a citizen .of the United States, residing at Chi cago, in the'oounty of Cook and'Stateof Illinois, have invented a new and useful 1m provement in; Speed-Regulating Mechanism for Gas-Engines, of which the following is a complete specification. i Y

. While this invention' relates, broadly, to

governors for gas-engines, it is more directly related to the-cone-actuated detent-lever for controlling thevalve mechanism thereof.

' 'Heretofore. in explosion-engines operating on the hit-and-miss principle and of the type in which the detent lever is actuated by a cone-sleeve on the crank-shaftit has been the practice to either arrange the cone-engagin roller to operate in a plane parallel with t e cone, as shown in Cook, No. 710,761, or in a plane at right angles thereto, as shown in Reynolds, No. 287,578. Such a construction is "objectionable, however, owing to the undue friction'resulting upon the bearing of. the small rollers or between the contacting surfaces of said rollersyand it is this objection which my improvement seeks to overcome.

Referring to the accompanying drawings, Figural represents a vertical longitudinal section-taken throu h the crank-shaft of the engine adjacent to t 1e detent-lever and associated arts, the view disclosing only such parts o a gas-engine as are deemed necessary to clearly illustrate the application of the improvement. Fig. 2 is afront and upper view showing the cone-sleeve on the crank-shaft and} the roller of the detent-lever resting thereon, the View being taken as indicated. by the line 2 2 in Figfl; and Fig; 3 represents a detail lan of the detentlever.

In t e drawings, 1 designates a portion of the en 'ne-frame, 2 the crank-shaft suitably journ ed thereon, and 3 a rocking arm piv otally supported at its lower end upon the engine-frame. The upper'end of the arm 3 serves as a-support and bearing for'the roller 4 and the forward end of the reciprocating valve-controlling bar 5. Since the operation of the valve-controlling rod in this combination is'well understood andas' no'claim to" Specification of Letters Eaterit. Application filed Ji ly10,.1905- seriallie. 2 68.927.-

' driven from the pinion 9 (indicated by dotted line in Fig. l) on thecrank-shaft 2 and thelatter. actuating the'valvewontrolling bar 5.

A, cone-sleeve 10 journals loosely upon the crank-shaft 2' and is longitudinally movable thereon. This cone-sleeve ispro'vided with the cone portion 10 and the slotted flanged extension 10 Which is engaged and. moved longitudinally on the crank-shaft by. the

governor-arms (not shown) in a manner Well understood. A detent-lever '11 is interposed between the forward end of the valve-contro lling bar 5 and the cone-sleeve 10, the said lefver being preferably offset, as shown, and

pivoted on the stud 12, the axis of which is arranged parallel with the axis .of the crank? shaft and; cone-sleeve. Oil/ the forward or cone-engaging end of the detent-lever 11 is. journaled a roller 13, the axis of which is arranged parallelwith respect to the contacting element of the cone-surface 10 on the conesleeve or interseotin with respect to the axis of the said sleeve. he result of this arrange- .ment will be to cause the pressure exerted by, the cone-sleeve 10 upon the roller 13 to be; received directu on the axis of the latter, and thus avoid a inding tendency :of

said roller on its bearing. It has beenfound that,when the roller and cone-sleeve were ar-,

ranged to operate in parallel planes the side pressure and binding tendency on the small rotating on its bearing, and in consequence the skidding actionwould soon wear aflat spot on its tread, thereby destroying or rendering.

roller would be sufficientto prevent it from largely avoided and the above-mentioned difiicultiesare completely overcome.

The manner in which a direct: pressure is exertedupon the roller 13 is illustrated in Fig. 2, in whichis shown, respectively, in dotted and full :lines the relative positions] of the cone-sleeve and roller before and'after a slight longitudinal movement of said sleeve.

- What I claim as my invention, and desire "to secure by Letters Patent, is- I,

1.;In a speed-controlling mechanism for gas-en I movab e cone-sleeve, a valve-controlhng bar, and a pivotally-mounted dete'nt-lever provided with a sleeve-engaging roller on the end thereof, the pivotal axis of said lever parines,incombination, alongitudinallyby said cone-sleeve forlocking against movement the said valve-controlling rod, the pivotal axis of said lever extending parallel with IO the longitudinal axis of said cone-sleeve, and

a sleeve-engaging roller mounted on the said lever, the axis thereof extending parallel with the contacting element of the cone-sleeve.

- GEORGE H. ELLIS.
